I. Product Overview

This multi-way low-voltage socket is manufactured using a pre-buried injection molding process with metal conductive pins, with the internal conductive pins made of high-elastic phosphor bronze precision stamping. The overall gold-plated layer isolates air oxidation, ensuring stable contact resistance after long-term insertion and removal. It can carry multiple low-voltage currents and weak electrical signals simultaneously. The external part is wrapped with flame-retardant and high-temperature-resistant PBT engineering plastic, offering excellent insulation and voltage resistance. It is resistant to high and low temperatures, oil stains, and is not easily cracked or deformed, making it suitable for use in vehicles and industrial equipment in environments with varying temperature differences.

Special anti-slip structure for socket cavity design, effectively preventing reverse insertion of the plug from damaging internal pins; one-piece elastic clips on both sides, securely locking after male and female mating, no plug disconnection or loose connection issues under vehicle vibration or equipment shock conditions; multiple bent metal welding tabs on the back, which can be directly mounted orWelding on the printed circuit board, with firm welding and convenient assembly, perfectly fitting the compact design for the narrow internal installation space of the equipment. The number of pins, outer dimensions, and clip style can be modified according to the customer's complete assembly requirements. The products are 1:1 copied from the physical prototypes, and after passing the durability, insulation withstand voltage, and salt spray corrosion tests in the early stage, mass production is carried out.

Chapter II: Core Highlights of Craftsmanship and Workmanship

1. Integrated needle insertion pre-buried injection molding, strong airtightness, moisture-proof and dust-proof
   The metal terminals are fully embedded within the plastic shell, without any joints or gaps, preventing moisture and dust from seeping into the cavity, significantly reducing the probability of terminal rusting and short-circuit failures.
2. Solid gold plated straight pin, lower temperature rise with high current conduction
   The bold solid conductive needle has a large contact area, strong current-carrying capacity, gold-plated surface with anti-oxidation and wear resistance, and does not wear or turn black after tens of thousands of insertions and extractions.
3. Flame-retardant high-temperature plastic shell, suitable for wide temperature working environment
   PBT flame-retardant material can withstand temperature changes within the range of -40℃ to 125℃, and can be stably used around vehicle engines and inside heating appliances, not easily softened or deformed under high temperatures.
4. Retainer clip + anti-backtracking double structure, secure and stable connection
   Anti-stupid positioning prevents incorrect insertion, elastic clip securely locks the plug, dual protection ensures stable wire connection, and eliminates power interruption noise caused by driving vibration.

Chapter 7: Common Procurement Q&A

Q1: Can the number of needles be increased or decreased at will?
A: Yes, mold injection production for various needle positions from 2P to 12P can be remolded.
Q2: For outdoor car usage under rain, how can rust and moisture resistance be optimized?
A: Choose thickened all-around gold-plated pin + waterproof lip edge cavity structure, significantly improving salt spray corrosion resistance time.
Q3: Can the insertion and removal tension be adjusted?
A: The insertion and removal feel can be precisely controlled by adjusting the diameter of the plug socket and the thickness of the pins.
Q4: Can the connector be made in a wire harness type (non-board welding)?
A: Support, both PCB welding and crimped wire harness outlet structures can be customized.
